Which can be a general form of a line with slope (0)?
Advertisement
Answer and explanation
Correct answer: \(y=5\)
A line with slope 0 is horizontal and has the form \(y=c\), where \(c\) is a constant. Therefore, \(y=5\) has slope 0. The slopes of \(y=5x\), \(y=x+5\), and \(y=-5x\) are 5, 1, and -5 respectively. Exam tip: In \(y=mx+c\), the coefficient of \(x\), namely \(m\), is the slope.
